There are many different types of lines, all characterized by their length being greater than their width. Lines can be static or dynamic depending on how the artist chooses to use them. They help determine the motion, direction and energy in a work of art. We see line all around us in our daily lives; telephone wires, tree branches, jet contrails and winding roads are just a few examples. Look at the photograph below to see how line is part of natural and constructed environments.

In this image of a lightning storm we can see many different lines. Certainly the jagged, meandering lines of the lightning itself dominate the image, followed by the straight lines of the skyline structures and the coast line. There are more subtle lines too, like the lights along the buildings. Lines are even implied by the reflections in the water.
The Nazca lines in the arid coastal plains of Peru date to nearly 500 BCE were scratched into the rocky soil, depicting animals on an incredible scale, so large that they are best viewed from the air. Let’s look at how the different kinds of line are made.
Diego Velazquez’s Las Meninas from 1656, ostensibly a portrait of the Infanta Margarita, the daughter of King Philip IV and Queen Mariana of Spain, offers a sumptuous amount of artistic genius; its sheer size (almost ten feet square), painterly style of naturalism, lighting effects, and the enigmatic figures placed throughout the canvas–including the artist himself –is one of the great paintings in western art history. Let’s examine it (below) to uncover how Velazquez uses basic elements and principles of art to achieve such a masterpiece.

Actual lines are those that are physically present. The edge of the wooden stretcher bar at the left of Las Meninas is an actual line, as are the picture frames in the background and the linear decorative elements on some of the figures’ dresses. How many other actual lines can you find in the painting?
Implied lines are those created by visually connecting two or more areas together. The gaze to the Infanta Margarita—the blonde central figure in the composition—from the meninas, or maids of honor, to the left and right of her, are implied lines. They visually connect the figures. By visually connecting the space between the heads of all the figures in the painting we have a sense of jagged implied line that keeps the lower part of the composition in motion, balanced against the darker, more static upper areas of the painting. Implied lines can also be created when two areas of different colors or tones come together. Can you identify more implied lines in the painting? Where? Implied lines are found in three-dimensional artworks, too. The sculpture of the Laocoon below, a figure from Greek and Roman mythology, is, along with his sons, being strangled by sea snakes sent by the goddess Athena as wrath against his warnings to the Trojans not to accept the Trojan horse. The sculpture sets implied lines in motion as the figures writhe in agony against the snakes.

Straight or classic lines provide structure to a composition. They can be oriented to the horizontal, vertical, or diagonal axis of a surface. Straight lines are by nature visually stable, while still giving direction to a composition. In Las Meninas, you can see them in the canvas supports on the left, the wall supports and doorways on the right, and in the background in matrices on the wall spaces between the framed pictures. Moreover, the small horizontal lines created in the stair edges in the background help anchor the entire visual design of the painting. Vertical and horizontal straight lines provide the most stable compositions. Diagonal straight lines are usually more visually dynamic, unstable, and tension-filled.

Expressive lines are curved, adding an organic, more dynamic character to a work of art. Expressive lines are often rounded and follow undetermined paths. In Las Meninas you can see them in the aprons on the girls’ dresses and in the dog’s folded hind leg and coat pattern. Look again at the Laocoon to see expressive lines in the figures’ flailing limbs and the sinuous form of the snakes. Indeed, the sculpture seems to be made up of nothing but expressive lines, shapes and forms.

There are other kinds of line that encompass the characteristics of those above yet, taken together, help create additional artistic elements and richer, more varied compositions. Refer to the images and examples below to become familiar with these types of line.
Outline, or contour line is the simplest of these. They create a path around the edge of a shape. In fact, outlines often define shapes.

Hatch lines are repeated at short intervals in generally one direction. They give shading and visual texture to the surface of an object.

Crosshatch lines provide additional tone and texture. They can be oriented in any direction. Multiple layers of crosshatch lines can give rich and varied shading to objects by manipulating the pressure of the drawing tool to create a large range of values.

Line quality is that sense of character embedded in the way a line presents itself. Certain lines have qualities that distinguish them from others. Hard-edged, jagged lines have a staccato visual movement while organic, flowing lines create a more comfortable feeling. Meandering lines can be either geometric or expressive, and you can see in the examples how their indeterminate paths animate a surface to different degrees.

Although line as a visual element generally plays a supporting role in visual art, there are wonderful examples in which line carries a strong cultural significance as the primary subject matter.
Calligraphic lines use quickness and gesture, more akin to paint strokes, to imbue an artwork with a fluid, lyrical character. To see this unique line quality, look up the work of Chinese poet and artist Dong Qichang, dating from the Ming dynasty (1555-1637). A more geometric example from the Koran, created in the Arabic calligraphic style, dates from the 9th century.
Both these examples show how artists use line as both a form of writing and a visual art form. American artist Mark Tobey (1890–1976) was influenced by Oriental calligraphy, adapting its form to the act of pure painting within a modern abstract style described as white writing.
A shape is defined as an enclosed area in two dimensions. By definition shapes are always flat, but the combination of shapes, color, and other means can make shapes appear three-dimensional, as forms. Shapes can be created in many ways, the simplest by enclosing an area with an outline. They can also be made by surrounding an area with other shapes or the placement of different textures next to each other—for instance, the shape of an island surrounded by water. Because they are more complex than lines, shapes are usually more important in the arrangement of compositions. The examples below give us an idea of how shapes are made.
Geometric Shapes, 11 July 2012, Creator: Oliver Harrison. CC BY
Referring back to Velazquez’s Las Meninas, it is fundamentally an arrangement of shapes; organic and hard-edged, light, dark and mid-toned, that solidifies the composition within the larger shape of the canvas. Looking at it this way, we can view any work of art, whether two or three-dimensional, realistic, abstract or non-objective, in terms of shapes alone.
Geometric Shapes vs. Organic Shapes
Shapes can be further categorized into geometric and organic. Examples of geometric shapes are the ones we can recognize and name: squares, triangles, circles, hexagons, etc. Organic shapes are those that are based on organic or living things or are more free form: the shape of a tree, face, monkey, cloud, etc.
Form is sometimes used to describe a shape that has an implied third dimension. In other words, an artist may try to make parts of a flat image appear three-dimensional. Notice in the drawing below how the artist makes the different shapes appear three-dimensional through the use of shading. It’s a flat image but appears three-dimensional.
When an image is incredibly realistic in terms of its forms (as well as color, space, etc.) such as this painting by Edwaert Collier, we call that trompe l’oeil, French for “fool the eye.”

Space is the empty area surrounding or between real or implied objects. Humans categorize space: there is outer space, that limitless void we enter beyond our sky; inner space, which resides in people’s minds and imaginations, and personal space, the important but intangible area that surrounds each individual and which is violated if someone else gets too close. Pictorial space is flat, and the digital realm resides in cyberspace. Art responds to all of these kinds of space.
Many artists are as concerned with space in their works as they are with, say, color or form. There are many ways for the artist to present ideas of space. Remember that many cultures traditionally use pictorial space as a window to view realistic subject matter through, and through the subject matter they present ideas, narratives and symbolic content. The innovation of linear perspective, an implied geometric pictorial construct dating from fifteenth-century Europe, affords us the accurate illusion of three-dimensional space on a flat surface, and appears to recede into the distance through the use of a horizon line and vanishing point(s). You can see how one-point linear perspective is set up in the examples below:
One-Point Linear Perspective, 11 July 2012, Creator: Oliver Harrison. CC BY
One-point perspective occurs when the receding lines appear to converge at a single point on the horizon and used when the flat front of an object is facing the viewer. Note: Perspective can be used to show the relative size and recession into space of any object, but is most effective with hard-edged three-dimensional objects such as buildings.
A classic Renaissance artwork using one point perspective is Leonardo da Vinci’s The Last Supper from 1498. Da Vinci composes the work by locating the vanishing point directly behind the head of Christ, thus drawing the viewer’s attention to the center. His arms mirror the receding wall lines, and, if we follow them as lines, would converge at the same vanishing point.

Two-point perspective occurs when the vertical edge of a cube is facing the viewer, exposing two sides that recede into the distance, one to each vanishing point.
Two-Point Perspective, 11 July 2012, Creator: Oliver Harrison. CC BY
View Gustave Caillebotte’s Paris Street, Rainy Weather from 1877 to see how two-point perspective is used to give an accurate view to an urban scene. The artist’s composition, however, is more complex than just his use of perspective. The figures are deliberately placed to direct the viewer’s eye from the front right of the picture to the building’s front edge on the left, which, like a ship’s bow, acts as a cleaver to plunge both sides toward the horizon. In the midst of this visual recession a lamp post stands firmly in the middle to arrest our gaze from going right out the back of the painting. Caillebotte includes the little metal arm at the top right of the post to direct us again along a horizontal path, now keeping us from traveling off the top of the canvas. As relatively spare as the left side of the work is, the artist crams the right side with hard-edged and organic shapes and forms in a complex play of positive and negative space.
The perspective system is a cultural convention well suited to a traditional western European idea of the “truth,” that is, an accurate, clear rendition of observed reality. Even after the invention of linear perspective, many cultures traditionally use a flatter pictorial space, relying on overlapping, size differences, or vertical placement of components in a two-dimensional work of art. Examine the miniature painting of the Third Court of the Topkapi Palace from fourteenth-century Turkey to contrast its pictorial space with that of linear perspective. It’s composed from a number of different vantage points (as opposed to vanishing points), all very flat to the picture plane. While the overall image is seen from above, the figures and trees appear as cutouts, seeming to float in mid air. Notice the towers on the far left and right are sideways to the picture plane. The trees and people occupying the upper parts of the image are meant to be perceived as further from the viewer as compared to those trees, buildings and people located near the bottom of the painting. This is an example of vertical placement.
As “incorrect” as it looks, the painting does give a detailed description of the landscape and structures on the palace grounds.

After nearly five hundred years using linear perspective, western ideas about how space is depicted accurately in two dimensions went through a revolution at the beginning of the 20th century. A young Spanish artist, Pablo Picasso, moved to Paris, then western culture’s capital of art, and largely reinvented pictorial space with the invention of Cubism, ushered in dramatically by his painting Les Demoiselles d’Avignon in 1907. He was influenced in part by the chiseled forms, angular surfaces and disproportion of African sculpture (refer back to the Male Figure from Cameroon) and mask-like faces of early Iberian artworks. For more information about this important painting, listen to the following question and answer.
In the early 20th century, Picasso, his friend Georges Braque and a handful of other artists struggled to develop a new space that relied on, ironically, the flatness of the picture plane to carry and animate traditional subject matter including figures, still life and landscape. Cubist pictures, and eventually sculptures, became amalgams of different points of view, light sources and planar constructs. It was as if they were presenting their subject matter in many ways at once, all the while shifting foreground, middle ground and background so the viewer is not sure where one starts and the other ends. In an interview, the artist explained cubism this way: “The problem is now to pass, to go around the object, and give a plastic expression to the result. All of this is my struggle to break with the two-dimensional aspect*”(from Alexander Liberman, An Artist in His Studio, 1960, page 113). Public and critical reaction to cubism was understandably negative, but the artists’ experiments with spatial relationships reverberated with others and became – along with new ways of using color – a driving force in the development of a modern art movement that based itself on the flatness of the picture plane. Instead of a window to look into, the flat surface becomes a ground on which to construct formal arrangements of shapes, colors and compositions. For another perspective on this idea, refer back to module one’s discussion of ‘abstraction’.
You can see the radical changes cubism made in George Braque’s landscape La Roche Guyon from 1909. The trees, houses, castle and surrounding rocks comprise almost a single complex form, stair-stepping up the canvas to mimic the distant hill at the top, all of it struggling upwards and leaning to the right within a shallow pictorial space.

As the cubist style developed, its forms became even flatter. Juan Gris’s The Sunblind from 1914 splays the still life it represents across the canvas. Collage elements like newspaper reinforce pictorial flatness.

It’s not so difficult to understand the importance of this new idea of space when placed in the context of comparable advances in science surrounding the turn of the nineteenth century. The Wright Brothers took to the air with powered flight in 1903, the same year Marie Curie won the first of two Nobel prizes for her pioneering work in radiation. Sigmund Freud’s new ideas on the inner spaces of the mind and its effect on behavior were published in 1902, and Albert Einstein’s calculations on relativity, the idea that space and time are intertwined, first appeared in 1905. Each of these discoveries added to human understanding and realligned the way we look at ourselves and our world. Indeed, Picasso, speaking of his struggle to define cubism, said “Even Einstein did not know it either! The condition of discovery is outside ourselves; but the terrifying thing is that despite all this, we can only find what we know” (from Picasso on Art, A Selection of Views by Dore Ashton, (Souchere, 1960, page 15).
Three-dimensional space doesn’t undergo this fundamental transformation. It remains a visual and actual relationship between positive and negative spaces.
5. Value and Contrast
Value (or tone) is the relative lightness or darkness of a shape in relation to another. The value scale, bounded on one end by pure white and on the other by black, and in between a series of progressively darker shades of grey, gives an artist the tools to make these transformations. The value scale below shows the standard variations in tones. Values near the lighter end of the spectrum are termed high-keyed, those on the darker end are low-keyed.
Value Scale, 11 July 2012, Creator: Oliver Harrison, CC BY
In two dimensions, the use of value gives a shape the illusion of form or mass and lends an entire composition a sense of light and shadow. The two examples below show the effect value has on changing a shape to a form.
The use of high contrast, placing lighter areas of value against much darker ones, creates a dramatic effect, while low contrast gives more subtle results. These differences in effect are evident in ‘Guiditta and Oloferne’ by the Italian painter Caravaggio, and Robert Adams’ photograph Untitled, Denver from 1970-74. Caravaggio uses a high contrast palette to an already dramatic scene to increase the visual tension for the viewer, while Adams deliberately makes use of low contrast to underscore the drabness of the landscape surrounding the figure on the bicycle.

Color is the most complex artistic element because of the combinations and variations inherent in its use. Humans respond to color combinations differently, and artists study and use color in part to give desired direction to their work.
Color is fundamental to many forms of art. Its relevance, use and function in a given work depend on the medium of that work. While some concepts dealing with color are broadly applicable across media, others are not.
The full spectrum of colors is contained in white light. Humans perceive colors from the light reflected off objects. A red object, for example, looks red because it reflects the red part of the spectrum. It would be a different color under a different light. Color theory first appeared in the 17th century when English mathematician and scientist Sir Isaac Newton discovered that white light could be divided into a spectrum by passing it through a prism.
The study of color in art and design often starts with color theory. Color theory splits up colors into three categories: primary, secondary, and tertiary.
The basic tool used is a color wheel, developed by Isaac Newton in 1666. A more complex model known as the color tree, created by Albert Munsell, shows the spectrum made up of sets of tints and shades on connected planes.
There are a number of approaches to organizing colors into meaningful relationships. Most systems differ in structure only.
Traditional color theory is a qualitative attempt to organize colors and their relationships. It is based on Newton’s color wheel, and continues to be the most common system used by artists.
Traditional color theory uses the same principles as subtractive color mixing (see below) but prefers different primary colors.The primary colors are red, blue, and yellow. You find them equidistant from each other on the color wheel. These are the “elemental” colors; not produced by mixing any other colors, and all other colors are derived from some combination of these three.The secondary colors are orange (mix of red and yellow), green (mix of blue and yellow), and violet (mix of blue and red).The tertiary colors are obtained by mixing one primary color and one secondary color. Depending on amount of color used, different hues can be obtained such as red-orange or yellow-green. Neutral colors (browns and grays) can be mixed using the three primary colors together.White and black lie outside of these categories. They are used to lighten or darken a color. A lighter color (made by adding white to it) is called a tint, while a darker color (made by adding black) is called a shade.
Think about color as the result of light reflecting off a surface. Understood in this way, color can be represented as a ratio of amounts of primary color mixed together. Color is produced when parts of the external light source’s spectrum are absorbed by the material and not reflected back to the viewer’s eye. For example, a painter brushes blue paint onto a canvas. The chemical composition of the paint allows all of the colors in the spectrum to be absorbed except blue, which is reflected from the paint’s surface. Common applications of subtractive color theory are used in the visual arts, color printing and processing photographic positives and negatives.The primary colors are red, yellow, and blue.The secondary colors are orange, green and violet.The tertiary colors are created by mixing a primary with a secondary color.Black is mixed using the three primary colors, while white represents the absence of all colors. Note: because of impurities in subtractive color, a true black is impossible to create through the mixture of primaries. Because of this the result is closer to brown. Similar to additive color theory, lightness and darkness of a color is determined by its intensity and density.
There are many attributes to color. Each one has an effect on how we perceive it.Hue refers to color itself, but also to the variations of a color.Value (as discussed previously)refers to the relative lightness or darkness of one color next to another. The value of a color can make a difference in how it is perceived. A color on a dark background will appear lighter, while that same color on a light background will appear darker.Saturation refers to the purity and intensity of a color. The primaries are the most intense and pure, but diminish as they are mixed to form other colors. The creation of tints and shades also diminish a color’s saturation. Two colors work strongest together when they share the same intensity.
Beyond creating a mixing hierarchy, color theory also provides tools for understanding how colors work together.
The simplest color interaction is monochrome. This is the use of variations of a single hue. The advantage of using a monochromatic color scheme is that you get a high level of unity throughout the artwork because all the tones relate to one another. See this in Mark Tansey’s Derrida Queries de Man from 1990.
Analogous colors are similar to one another. As their name implies, analogous colors can be found next to one another on any 12-part color wheel:
You can see the effect of analogous colors in Paul Cezanne’s oil painting Auvers Panoromic View
Colors are perceived to have temperatures associated with them. The color wheel is divided into warm and cool colors. Warm colors range from yellow to red, while cool colors range from yellow-green to violet. You can achieve complex results using just a few colors when you pair them in warm and cool sets.
Complementary colors are found directly opposite one another on a color wheel. Here are some examples:purple and yellowgreen and redorange and blue
Blue and orange are complements. When placed near each other, complements create a visual tension. This color scheme is desirable when a dramatic effect is needed using only two colors.
At the most basic level, Three-dimensional works of art (sculpture, pottery, textiles, metalwork, etc.) and architecture have actual texture which is often determined by the material that was used to create it: wood, stone, bronze, clay, etc. Two-dimensional works of art like paintings, drawings, and prints may try to show implied texture through the use of lines, colors, or other ways. When a painting has a lot of actual texture from the application of thick paint, we call that impasto.
The first image below is a sculpture, and like all three-dimensional objects it has actual texture.

The next two images are details from the painting The Arnolfini Portrait by Jan van Eyck. Here, the artist has created implied texture. If you were to touch this painting you would not feel the fabric of the clothing and carpet, the wooden floor or the smooth metal of the chandelier, but our eyes “see” the texture.
